Dear all,

First, I would like to thank S. Falcon, J.W. MacDonald and J. Zhang for
help on my previous questions.

I want to use the function hyperGTest on arabidopsis data, but it seems
that there is a little bug
in this function. This is an example that gives me an error message
(hereafter, allegenes is a vector
of selected genes)

genesel<-c("AT1G55530", "AT5G19770" ,"AT4G10840")

Then if I execute the command

I obtain the error message:

Erreur dans order(na.last, decreasing, ...) :
        l'argument 1 n'est pas un vecteur
        (argument 1 is not a vector)

I supposed that the error comes from the fact there is no GO term in the
category BP for my
three genes...I tried to make some filters in such cases, but without

The different versions I use are :
R version 2.4.0
ath1121501' version 1.14.0
GOstats' version 2.0.2
GO version 1.14.0

Thanks for your help,
